Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a foam that gives the icing its light, airy structure.
- Sugar
- Dissolved into a syrup that sweetens the icing and helps it set glossy.
- Citric acid
- Adds a little tartness that balances the sweetness.
The step that matters
Pouring the syrup into the whites. Pouring the hot syrup slowly into the whites while beating keeps it from clumping or scrambling and lets the whites stiffen into a smooth, glossy icing. Keep beating until the icing has cooled and holds its shape.
